Freshest data APIs for AI agents — 850M+ people, 40M+ companies, verified contacts, reverse email lookup, and real-time LinkedIn data at a fraction of competitor pricing.

Pros

  • + First-class agent support — official MCP server, Python/TypeScript SDKs, and dedicated agentic search endpoints that convert natural language to structured filters
  • + Comprehensive OpenAPI 3.1 spec (90+ endpoints) makes tool-use integration trivial for LLM function calling
  • + Unique endpoints competitors lack: reverse email-to-person lookup, real-time LinkedIn live fetch, kitchen-sink enrichment, and GitHub-to-LinkedIn resolution

Cons

  • - No permanent free tier — only a 7-day trial, then minimum $300/mo
  • - Auth is non-standard (apiKey in request body for POST, query param for GET) rather than a standard Authorization header, requiring custom handling in generic API clients
